Are you perchance talking about deSEC? I've also switched to them, and thought that it was too much work to send an email and wait for replies, so I ended up using dummy inboxes for my other, lesser important domains.

Though I guess it's still a good thing they do this? At the time I remember being mildly inconvenienced, but not enough to actually care. I just remember thinking, "How is this nonprofit going to handle all that support volume?".
